Monoprice

This last week was SEFF, a week of electric-powered remote-controlled aircraft above 1700 feet of Bermuda grass in the middle of Georgia. [Damon Atwood] has been bringing his 16-foot-wingspan Emmaselle to SEFF for a few years now, and this year we’re getting a great video of the flight. This is, or was at one time, the 3rd largest electric RC on the planet. It’s flying on 11S, and is absolutely beautiful in the air.

One of the very inexpensive 3D printers announced at CES by Monoprice is now on sale. It’s the improved $200 Cartesian, not the $150 delta. As I saw at CES last January, this is a slight improvement over the already fantastic V1 version of this printer. Improvements include an all metal hot end (an E3D clone) and working WiFi on the main board. Still waiting on the $150 delta printer? The only thing I can tell you is that it’s coming out soon.

StippleGen is an application from Evil Mad Scientists Labs to create stippled drawings. Stippling is dots, but not halftone. [HEXceramic] is using StippleGen to create laser cut molds for making ceramic tiles. The results look awesome, and I can’t wait to see one of these fired.

Hackaday has been voted, ‘The Hacker News of Hardware‘ by the Hacker News community. I would have included this in the links post last week, but feared that would be seen as manipulating the upvote system on Hacker News. This is great, but of course you already know Hackaday is seen as a reputable source of hardware and embedded news!

As a rule, Hackaday is nonpartisan and not political at all. In fact, two of my headlines have been shot down so far this year for using the word ‘trump’ as a verb. You’re welcome. This project is too cool, so we’re going to bend a few rules. This is a Trump gummi. It’s the rarest gummi of them all. It was carved by gummi artisans who work exclusively in the medium of gummi.

[Michael Welling] designed the PocketBone Mini in KiCad. It’s built around the Octavo Systems OSD3358, and is really, really tiny while designed to be as capable as a full size BeagleBone. He’s doing an interest check to gauge the community’s interest in this tiny, tiny single board computer.

CES is over, and now we can take a step back, distance ourselves from the trade show booths, and figure out where 3D printing will be going over the next year.

The Hype Cycle is a great way to explain trends in fads and technological advances. VR and autonomous cars are very early on the Hype Cycle right now. Smartphones are on the plateau of productivity. 3D printing is head-down in the trough of disillusionment.

For this year’s CES, 3D printing is not even a product category. In fact, the official documentation I found at Prusa’s booth listed their company in the ‘Assistive Technologies’ category. These are dark days for the public perception of 3D printing. The source of this perception can be brilliantly presented in a pair of graphs:

The perception of 3D printing has been tied inexorably to Makerbot. Makerbot presented the only 3D printer on The Colbert Report. Only Makerbot had their 3D printing storefronts featured on CNN. It’s been like this for half a decade, and hopefully things will get better.

This doesn’t mean 3D printing isn’t improving. In fact, it’s the best it’s ever been. CES had the most innovative printers I’ve seen in years. I caught a glimpse of this year’s top-selling printer (and it launches in April). Resin machines are going to be very popular soon. What did CES have to offer? Check it out below.

At CES last year, Monoprice introduced a $200 3D printer. Initial expectations of this printer were middling. My curiosity got the best of me, and last summer I picked up one of these printers for a review. The Monoprice MP Select Mini is actually phenomenal, and not just ‘phenomenal for the price’. This machine showed the world how good one of the cheapest printers can be. The future is looking awesome.

You might think Monoprice wouldn’t be able to top the success of this great little machine. You would be wrong. This week, Monoprice announced a bevy of new and upgraded printers. Some are resin. Some are huge. One will sell for $150 USD.

The holidays are almost here, and with that comes the traditional Mass Consumption of Consumer Goods and Gift Exchange. 3D printers are getting really good and really cheap, and it’s inevitable that a lot of 3D printers will be given as gifts this year. Be careful if you’re giving or receiving one of these printers: they can cause fires as [Ben Hencke] found out when diagnosing a problem with a printer he bought this year.

The printer in question is the Monoprice Maker Select V2, a Prusa i3 clone with impressive specs for a $300 printer. This printer is a rebranded Wanhao Duplicator i3, and we’ve reviewed it favorably. It’s a capable printer that beats the pants off of any Kickstarter printer in quality (and for the fact that you can buy it right now). We’re pretty sure there are going to be more than a few of these printers under the Saturnalia tree this year.

After a few weeks, [Ben] noticed a bit of smoke coming from the printer while the bed was preheating. This wasn’t blue pixie smoke, like you’d find from an exploded capacitor. There was a lot of smoke.

After a closer inspection and help from [Elecia White] from embedded.fm, the problem was traced to the power connector for the heated bed. The green, bromine-infused plastic for this connector was charred and there’s little doubt this could have caused a fire.

3D printing is a fantastic tool, and has enabled more hacks and builds over the last few years than we could have ever imagined. 3D printers are getting very good, and very cheap, and of course this will eventually mean someone losing their workshop to a printer fire. Until someone figures out how to build a ‘thermal fuse’ or something of that nature, 3D printers — from the high-end ones to the still very good Monoprice and Wanhao units — have the potential to start a fire.

[hirocreations] printed an entire suit of enormous Fallout power armor on his Monoprice Maker Select 3D printer, which took some 140 days and over 120 pounds of IC3D PLA filament. Happily, [hirocreations] was able to arrange a sponsorship with IC3D for the build – who would be crazy enough to use so much filament over so long for an entire 7+ foot tall suit, right? Over those 140 days, the belts on the printer needed to be replaced twice but it otherwise chugged right along.

Most of the parts were printed at 0.46 mm layer height. Individual parts were welded (melted) together using what is essentially a soldering iron with a flat tip; many parts were too thin for any kind of joints or fixtures to be practical. Parts were smoothed with drywall spackle, lots of filler primer, and painted. Some of the parts – like the chest armor – are mounted on a frame made from PVC tubing. [hirocreations] may have gone through 120 pounds of filament, but the end result doesn’t weigh that much; the suit itself weighs in at 85-90 lbs, the rest of it went to support material, skirts, and print failures.

It was known from the start that weight could become a serious issue, so [hirocreations] went for a very light infill (10%) and 3-4 perimeter layers; he also extruded at a high temperature (~230C) which he said seemed to provide a very strong layer bond with the settings and filament he was using. So far, he says it’s taken some very hard knocks and nothing has broken or cracked. He has a short video series documenting the assembly, and you can see some of the raw armor parts before any finishing in one of the videos, embedded below.

A few months ago, a very inexpensive 3D printer appeared on Monoprice. My curiosity for this printer was worth more than $200, so I picked one of these machines up. The Monoprice MP Select Mini is an awesome 3D printer. It’s the perfect printer to buy for a 13-year-old who might be going through a ‘3D printing phase’. It’s a great printer to print a better printer on. This printer is a sign the 3D printing industry is not collapsing, despite Makerbot, and foreshadows the coming age of consumer 3D printers.

The MP Select Mini isn’t Monoprice’s only 3D printer; the printer I bought was merely the ‘good’ printer in the good-better-best lineup. Since my review of the MP Select Mini, Monoprice has introduced their top of the line, the Maker Ultimate 3D printer. Monoprice asked if I would like to take a look at this offering, and I’m more than happy to oblige.

After a week of burn-in, I can safely say you’re not wasting your money on this $700 3D printer. It’s not a starter printer — it’s one that will last you a long time. 2016 is the beginning of the age of consumer 3D printers, and the Monoprice Maker Ultimate is more than proof of this.

Two weeks after my review of the MP Select Mini 3D printer, Monoprice’s own website has said this printer has been out of stock, in stock, and out of stock again several times. This almost unimaginably cheap 3D printer is proving to be exceptionally popular, and is in my opinion, a game-changing machine for the entire world of 3D printing.

With the popularity of this cheap printer that’s more than halfway decent, there are bound to be improvements. Those of us who have any experience with 3D printers aren’t going to be satisfied with a machine with any shortcomings, especially if it means we can print enhancements and mods for our printers.

Below are the best mods currently available for this exceptional printer. Obvious problems with the printer are corrected, and it’s made a little more robust. There are mods to add a glass build plate, and a few people are even messing around with the firmware on this machine. Consider this volume one of the MP Mini hacks; with a cheap printer that’s actually good, there are bound to be more improvements.
